1JWL-2 Secondary Air Microbial SamplerCharacteristics:

The serious harm caused by air microbial pollution has received increasing attention today, making the need for sampling and monitoring of various air pollutants even more urgent. The quantity and size distribution of air microorganisms are two * indicators for evaluating the hazards. The JWL-2 air microorganism sampler produced by our factory can not only measure the quantity of air microorganisms, but also the size of these particles, which is one of the important indicators for determining the harm of air microorganisms. He is composed of six machines combined into one, and each stage is actually a single-stage sampler. Using the principle of two repeated impacts, the vast majority of particles, especially those settling in organs and lungs, are basically impacted. Therefore, the particle size range it collects is naturally wider than that of single-stage impact samplers. The circular nozzle of the impactor has a higher sampling efficiency than the slotted nozzle. The relative humidity gradually increases during sampling, which is very beneficial for the survival of fragile pathogenic microorganisms, especially virus particles, and has been commonly used since its inception.

IIJWL-2 Secondary Air Microbial SamplerPurpose:

JWL-2 Secondary Air Microbial SamplerIt can be widely used for sampling and monitoring the quantity and size distribution of air microorganisms in environments such as disease prevention and control, environmental protection, pharmaceuticals, fermentation industry, food industry, and biological cleanliness. It can also be used for sampling and research on air microorganisms in relevant scientific research and teaching departments, providing scientific basis for evaluating the hazards of environmental air microbial pollution and its control measures.
